Question — Will lime sulphur kill the eggs? 



Answer — No, I think not but the old home-made lime-sulphur seemed 

 to prevent the settling down of the young lice after they had hatched. 



Question — It has been stated that saH and water would do this. 



Answer — No, it will not kill the eggs. Even lime and sulphur will 

 not kill many of them. There is nothing known at present which will 

 kill the plant lice eggs without injuring the buds and if we get a 

 cold, wet spring tlie parasites are held back so that the plant lice 

 multiply and get such a start that they last all summer. 



A Member — What is a remedy? 



Answer — Dry, warm weather, — for spraying purposes lime and sul- 

 phur are of no use after the leaves come out. Whale oil soap costs 

 too much. Probably the most efficient spray is nicotine. It costs 

 a great deal but I do not know of anything that will take its place. 

 It is at least safe. 



Question — How strong? 



Answer — One to seven hundred parts. 



Question — What time should we use it? 



Answer — That depends on the weather. Two years ago we received 

 a great many requests for information about this same thing. The 

 eggs were thick and were hatching out and Ave took a chance on spoil- 

 ing our reputation and guessed that the lice would not be very bad. 

 We guessed that way because the spring had been warm and dry and 

 we hoped that the parasites would take care of the lice if they were 

 let alone. We advised the people not to spray unless they felt worried 

 about it and it turned out all right. This past season started in with 

 lots of eggs hatching into lice but the weather had been cold and wet 

 and we advised the use of some contact spray, nicotine, kerosene emul- 

 sion, tobacco tea or something of the sort. 



Question — Can you mix this nicotine with lime-sulphur? 



Answer — You do not want to mix lime-sulphur with anything until 

 you are ready to put it on. It is claimed by the makers that you can 

 mix nicotine sulphate with lime-sulphur safely if you do it just be- 

 fore you apply the spray. 



Mr. Hutchins — The government is conducting an experiment in our 

 section during the past summer and fall on one of the places there, 

 and carrying it out with that same idea. They put on the arsenate of 

 lead, and lime-sulphur at ordinary strength, and carried it with a high 

 pressure and forced the spray right down onto the trees, which were 

 low, and they did not give them another application for the codling 

 moth. One spray after blossoming was given and they omitted the 

 summer spray for the codling moth, and comparing that with the others, 

 I have forgotten just the proportion — there was not a decided ad 

 vantage with the summer spray. 



The Chairman — The next topic on the program for discussion is one 

 that Ave should all feel deeply interested in — one that should appeal to 

 every fruit groAver in the State of Michigan, and every fruit grower 

 in the United States, and that is the neAv Sulzer Apple LaAV, and we 

 will hear from Mr. R. G. rhillips, Secretary of the International Apple 

 Shippers' Association.
